Chat that we had today :)

	const printMatrix = (matrix) => matrix.forEach((line,j) => console.log('('+j+')',line));

	// USES ALGORITHM THAT I DESCRIBED WHICH WAS WRONG!!!!
	const countIslandsMyAlgorithm = (matrix) => {
	const checkCounterMatrix = (counterMatrix,i,j) => {
	if((i-1 >= 0) && (counterMatrix[i-1][j] !== 0)) return counterMatrix[i-1][j];
	if((j-1 >= 0) && (counterMatrix[i][j-1] !== 0)) return counterMatrix[i][j-1];

	// this 2 cases are never considered in any of the matrices, this causes issues
	if((i+1 < matrix.length) && (matrix[i+1][j] !== 0)) return counterMatrix[i+1][j] = 0;
